EV charging information and connectivity

What does EV-17 measure?

EV-17 is a smart-ready service within the Smart Readiness Indicator (SRI), the European measurement tool for the digital readiness of buildings. This service falls under the electric vehicle charging domain and assesses the extent to which a building provides information about the charging process and whether the system automatically recognises the driver.

The service forms part of method A, the simplified assessment method of the SRI. This means EV-17 is also included in a shortened assessment, alongside the detailed method B.

What functionality levels exist?

The SRI has functionality levels for each smart-ready service that express the degree of readiness. For EV-17 there are three levels, numbered from 0 to 2.

• Level 0: No information is available about the charging process.
• Level 1: The system reports information about charging status to the user, for example how far charging has progressed.
• Level 2: In addition to reporting on charging status, the system automatically recognises the driver at the charging point. This occurs according to ISO 15118 standard, an international standard for communication between vehicle and charging infrastructure.

Why does this service count towards the score?

Each smart-ready service is assessed in the SRI against seven impact criteria, such as energy efficiency, comfort and convenience, and information for residents and building managers. The functionality level of EV-17 contributes to the building's overall score.

That score is expressed as a percentage and classified into one of seven classes, from below 20 percent to 90 to 100 percent. Services related to electric vehicle charging carry weight alongside services in the other eight SRI domains.

How does EV-17 relate to broader regulation?

The SRI is incorporated into the Energy Performance of Buildings Directive (EPBD) and is currently voluntary. The European Commission must adopt a delegated act by 30 June 2027 that is expected to make the SRI mandatory for non-residential buildings with installations above 290 kW.

Separate from the SRI, article 13 of the EPBD already requires building automation above certain power thresholds, which in practice encourages the use of services such as EV-17.
